WordPress crash after update to 3.4

Immediately after updating the plugin to version 3.4, my WordPress 7.1.2 crashed, and I had to rename the plugin folder to get everything working again.

Here is the server log:

Un errore di E_ERROR è stato causato nella linea 1146 del file /web/htdocs/http://www.huddle.org/home/wp-content/plugins/tablepress/controllers/controller-frontend.php.
